Dear Joe Shia: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

Accurate Multi Panel Drug Urine Test Cup offers any combinations from 2 to 15 drugs of abuse tests but only
one cutoff concentration under same drug condition will be included per device. It is for in vitro diagnostic
use only.
The tests may yield positive results for the prescription drugs Buprenorphine, Nortriptyline, Oxazepam,
Secobarbital, Propoxyphene, and Oxycodone when taken at or above prescribed doses. It is not intended to
distinguish between prescription use or abuse of these drugs. Clinical consideration and professional judgment
should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result.
The tests provide only preliminary results. To obtain a confirmed analytical result, a more specific alternate
chemical method must be used. GC/MS or LC/MS is the recommended confirmatory method.
8. Device Description

10. Test Principle
Accurate® Multi Panel Drug Urine Test Cup is a rapid test for the qualitative detection of Amphetamine,
Buprenorphine, Secobarbital, Oxazepam, Cocaine, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine,
Methamphetamine, Methylenedioxymethamphetamine, Morphine, Methadone, Oxycodone,
Phencyclidine, Propoxyphene, Nortriptyline and Marijuana in urine samples. They are lateral flow
chromatographic immunoassay. When urine sample is added to the cup device, urine is absorbed into the
test strip and migrates upwards by capillary action. If the concentration of target drug presented in the
urine sample is below the cutoff level, the target drug will not saturate the binding sites of its specific
monoclonal antibody-coated particles. The antibody-coated particles will then be captured by
immobilized drug-conjugate and a visible colored band will be formed on the test line region. If the
concentration of target is beyond the cutoff level, the target drug will saturate the binding sites of its
specific monoclonal antibody-particles, thus the antibody-coated particles will not be captured by
immobilized drug-conjugate hence no colored band will be formed on the test line region.
A band should be formed on the control line region regardless of the presence of target drug or metabolite
in the sample to indicate that the tests have been performed properly.

f. Effect of Urine Specific Gravity and Urine pH
To investigate the effect of urine specific gravity, urine samples with specific gravity from 1.000 to
1.035 were spiked with target drugs at +50% cutoff and -50% cutoff levels. Three operators tested
samples using test devices from three different lots. The results were all positive for samples at
+50% cutoff and all negative for samples at -50% cutoff, indicating that urine specific gravity
between 1.000 and 1.035 has no effect on the accuracy and precision of the test device.
To investigate the effect of urine pH, urine samples with pH value from 4 to 9 were spiked with
target drugs at +50% cutoff and -50% cutoff levels. Three operators tested samples using test
devices from three different lots. The results were all positive for samples at +50% cutoff and all
negative for samples at -50% cutoff, indicating that urine pH value between 4.0 and 9.0 has no
effect on the accuracy and precision of the test device.

2. Comparison Studies
The method comparison studies for Accurate® Multi Panel Drug Urine Test cup were performed in-
house with three operators.
Operators ran 80 (40 negative and 40 positive) unaltered urine samples. The samples were blind
labeled and compared to LC/MS or GC/MS results. The results are presented in the table below:

Lay-user study:
184 males and 126 females tested Accurate® Multi Panel Drug Urine Test Cup Configuration 1
(including MOP 300); 178 male and 132 females tested Accurate® Multi Panel Drug Urine Test Cup
Configuration 2 (including MOP 2000 (OPI). They had diverse educational and professional
backgrounds and fluent in English and their age range from 20 to over 50. Urine samples were
prepared at the following concentrations; -100%, +/-75%, +/-50%, +/-25% of the cutoff by spiking
drug(s) into drug free-pooled urine specimens. The concentrations of the samples were confirmed by
LC/MS. Each sample was aliquoted into individual containers and blind-labeled. Each participant
was provided with the package insert, 1 blind labeled sample and a device. The results are
summarized below.
